Section II. EQUIPMENT DESCRIPTION AND DATA 



18. EQUIPMENT CHARACTERISTICS, 
CAPABILITIES, AND FEATURES. 



The M9 pistol is a semiautomatic, magazine fed, recoil 
operated, double action pistol, chambered for the 9mm 
cartridge. 



WARNING 

Pistol will fire from the half cock position if 
the trigger is pulled. 



a. Double Action. When a round is in the 
chamber with the safety on and the hammer down, 
double action allows the pistol to fire by placing the 
safety in the fire postion and pulling the trigger. 

b. Magazine. Has a 15 round capacity. 



c. Extractor! Loaded Chamber Indicator. When 
there is a round in the chamber, the upper surface of 



the extractor protrudes from the right side of the slide 
In the dark, the protrusion can he felt by touch. 



WARNING 

A potential safety hazard exists if the firing 
pin Mock is missing or does not return flush 
with the slide surface after fifing. 



d. Firing Pin Block. When the trigger is not 
pulled, the fifing pin block secures the firing pin and 
prevents it from moving forward, even if the pistol is 
dropped. 

e. Ambidextrous Safety. Allows safe operation 
of the pistol by both right and left handed users, and 
lowers the hammer without causing an accidental 
discharge. When the safety is in the up position, the 
pistol is ready to fife. When hammer is cocked, it may 
be safely lowered by moving the safety to the safe 
(down) position. 



f. Lanyard Loop. Compatible with standard 
lanyards. 

8. Receiver. The front and back straps of the 
grip are vertically grooved to ensure a firm grip even 
with wet hands, or under conditions of rapid combat 
fire. The trigger guard is extended, and the concave 
forward portion is grooved for a firm grip when using 
two hands or gloves. 

h. Disassembly Lever and Disassembly Button 

Allows for quick field stripping, and at the same time 
prevents accidental disassembly. 

i. Slide Stop. Holds the slide to the rear after 
the last round is fired. It can also be manually 
operated.

Section III. PRINCIPLES OF OPERATION 



1 13. GENERAL. 



a. The M9 pistol has a short recoil system utilizing 
a falling locking block. 



b. Opon firing, the pressure developed by the 
combustion gases recoils the slide and barrel assembly. 
After a short run, the locking block will stop the 
rearward movement of the barrel and release the slide 



which will continue its rearward movement. The slide 
will then extract and eject the fired cartridge case, 
cock the hammer and compress the recoil spring. The 
slide moves forward under recoil spring pressure feeding 
the next round from the magazine into the chamber. 

c. The slide stop holds the slide and barrel 
assembly open after the last round has been fired and 
ejected.

raise the pistol in a line parallel to the barrel (71 until 
the fixture and weights are suspended. 

8. The hammer (41 must not fall. If the hammer falls, 
the trigger pull is too light and the sear and/or hammer 
must be replaced. Replace the sear and/or hammer in 
accordance with the maintenance procedures provided in 
paragraph 3 11. !f replacement of hammer and(or sear 
fails to correct light trigger pull, inspect main spring for 
correct free length. Replace if necessary.

is reached. Hold the pistol (5) in a vertical position. 
Place the end of the test fixture (1) over the trigger 
(6). Slowly raise the pistol in a line parallel to the 
barrel (7| until the fixture and weights are suspended. 
The hammer (4) shall move back slowly to the cocked 
position, then release and snap forward quickly. If the 
hammer does not meet these requirements, replace the 
sear and/or hammer (see para 3 1 1) and retest.

| FUNCTION FIRING TEST 



WARNING 

Before performing the function-fire test, be 
sure to clear the pistol. Do not squeeze the 
trigger until the pistol has been cleared. 
Inspect the chamber to be sure that it is 
empty. Check to see that there are no 
obstructions in the barrel. 



1. If possible, upon completion of maintenance 
procedures, the M9 Pistol should be function-fired to 
assure proper operation, 

2. Fire three rounds in single action. 



3. Fire three rounds in double action. 

4. If a test firing facility or live ammunition is not 
available, use dummy ammunition to check chambering, 
extraction, and ejection. 



WARNING 

Be sure pistol is clear and there are no 
obstructions in the barrel or chamber. 



5. Upon completion of function-firing test, clean and 
lubricate the pistol in accordance with paragraph 3 8 or 
the operator's manual.

a. Inspection Criteria. 



WARNING 

Before starting an inspection, be sure to 
clear the weapon. Make sure the magazine 
is removed, the pistol is clear of ammunition 
and the barrel has no obstructions. 



(1) Before inspection, the materiel must be 
thoroughly cleaned of all grease, dirt, or other foreign 
matter that might interfere with its proper function or 
the use of gages and tools during inspection. 



(21 The pistol must be free of burrs, rust, or 
corrosion. 

(31 Parts must not be loose, cracked, bent, 
distorted, or damaged and must be free of excessive 
wear. 

(4) Minor defects in metal components do not 
normally affect their acceptability. For example, tool 
marks are ordinarily of no importance. 

[5\ Inspect finish of metal surface. Satisfac- 
tory metal surfaces for weapons range from black to 
light gray. Weapons will be rejected if exterior parts 
have a reflective shine. Sights must have a dull gray 
or black finish on surfaces that would cause glare.

3 14. PREEMBARKATION OF MATERIEL IN UNITS 
ALERTED FOR OVERSEAS MOVEMENT (cont) 



b. Inspection Areas. 

(1) Springs must be free of distortion and 
broken coils. Springs must have sufficient tension to 
perform their intended function. 

(2) Barrel must he clean and free of rust and 
corrosion. 

(3) Barrel must not be bulged. 

(4| Pits in the bore are allowable if they 
do not exceed the width of a land and 3/8 inch in 
length. 

(5) If chipping and flaking are present in the 
chamber and/ar bore area, it is cause for rejection of 
the barrel. 

{6} Tool marks are acceptable. They may 
appear as lines running longitudinally in the grooves or 
may run spirally across the tops of lands. 

(7) Lands that appear dark will not be cause 
for rejection because of coating of guilding metal from 
projectiles. 



{8) The sear and cocking notches must be in 
good condition. Chipped engaging corners will be cause 
for rejection. Slight wear on functional surfaces, 
including engaging corners, shall be acceptable, 
providing the minimum trigger pull requirements are met. 

(9) Chips, flat spots, pits or bent strike points 
on firing pins will be cause for rejection of firing pins. 

(10) The cartridge case engaging surfaces on 
the extractor must not be chipped or deformed. 

(11| The safety must position positively in both 
the safe {down! and fire (up} position. When in the 
safe position, the pistol must not fire when the trigger 
is squeezed; when in the fire position, the pistol must 
fire when the trigger is squeezed. 

(1 2) Each pistol must be hand functioned to 
check for unusual binding, positive cocking action, and 
general operation. Dummy ammunition may be used to 
be sure of positive chambering, extraction, and ejection 
action.
